Powder Coating & Restoration Resource for Vintage Chairs?

Q: I am looking into restoring vintage patio chairs (larger photo below) that were inherited from my husband's grandparents. We think they are from the 50's. I'm looking for a company to powder coat and re-strap with vinyl cording in SF Bay Area. The one company I found no longer works with the type of strap that is original to the chairs. Are there other companies that are willing to do this work?

Also any idea what company manufactured these chairs? The company I spoke to thought they were from the Walter Lamb Bronze collection but the metal doesn't look bronze to me and doesn't match any of the photos of the collection I have found online. Thanks in advance for any tips you can provide!
